Great watch
Color: Blue on Blue Rubber
Beautiful watch with great value for price and very comfortable. Only issue is the brightness of the dial in the dark, it's very low and can be difficult to read when it's dark out. Other than that I have no notes

Where have these watches been?
Color: Grey on Black Fabric
A wonderful looking and wearing (with some wee modifications)watch. I originally bought this watch with the textile band but soon discovered it was not a marriage made in heaven. I swapped the bracelet for a leather aftermarket deployment bracelet and it transformed the watch for me.

Great Swiss Watch
Color: Green on Stainless Steel
High build quality. Super smooth movement. I've found that it loses time a lot faster than many of my Japanese automatics. The color options are great, but I wish there was more bracelet color diversity. High quality steel doesn't scratch easily. The date complication is awesome.
